Abstract
Aims
To explore the impact of pictorial image and teach back educational strategies on
knowledge, adherence to medication and diet among patients with type 2 diabetes and
low health literacy in Saqqez, Iran.
Methods
In this randomized controlled trial, 127 patients with type 2 diabetes who had low
health literacy were randomly allocated into three arms of the study (pictorial image,
teach back, and control groups). The two intervention groups received education within
three weekly sessions, each lasting 20 min. The level of functional health literacy in adults (TOFHLA), diabetes knowledge,
and adherence to medication and diet were measured and compared in the three groups
before and six weeks after the interventions. We used intention to treat analysis.
Data were analyzed using ANOVA and Paired t test.
Results
Mean scores of knowledge, adherence to medication and diet revealed significant differences
between two intervention groups and control group (P < 0/001) six weeks after intervention.
Conclusions
Both educational strategies increased knowledge, as well as adherence to medications
and diet among patients with type 2 diabetes and low health literacy. Both educational
strategies seem to be effective for patients with low health literacy and are recommended
to be used according to patients’ conditions.
